Whisk the egg in a bowl and mix in the buttermilk.
Put all the dry ingredients together in a medium bowl.
Form a well in the centre and pour in the liquid. Whisk the liquid into the dry and get rid of the lumps.
Melt butter or oil into the pan and add 2-3 large spoonful of batter across the pan. About 10cm spread. Bubbles will appear on the top and burst. You can add fruit at this point, then flip.
Repeat with remaining batter, keeping finished pancakes on a heatproof plate in oven. Serve warm drizzled with blueberry pie filling sauce. Crispy bacon is also a delicious addition.
